I've seen several references to this problem elsewhere, but wonder if anyone has a good solution to it. Here's the story:
I'm just wondering what experience other people have had with this and what they've done about it.
- I've begun shooting a GPR that I inherited from my son, and I really like the gun. But the nipple situation is driving me a bit crazy.
- With the standard Lyman nipple, I can't seem to find a type of #11 cap that will will fit tightly. This is inconvenient and potentially a bit unsafe.
- I have now tried two different aftermarket nipples (one from TOW and one from Oxyoke). They're stainless, and I'd like to use a stainless nipple if I can get one to work for me.
- With these nipples, the caps fit on tightly, BUT ...
- Once the nipple is on, I can't put the gun into half-cock. This is quite unacceptable to me, especially since I'm starting to shoot in matches on a regular basis.
- After quite a bit of trial and error, and measurement, I've discovered that the aftermarket nipples are taller than the Lyman ones. Measured from the base of the nipple that seats against the lock (i.e., at the top of the thread) to the top of the nipple, the Lyman nipple measures about 0.385" and the other nipples measure about 0.455". The result is that once the cap is on the taller nipple, the hammer can't fall far enough to reset for putting into half cock.
- So I seem to be in a situation where I can either put the hammer in half cock OR I can have a tightly seated cap, BUT NOT BOTH.
I'm just wondering what experience other people have had with this and what they've done about it.
